Nah, Cops are useless even for things that are a decade old like Find My iPhone, they simply won't help even if you can give them the exact lat/long or address.
I've dealt with cops when helping a friend who was being harassed (literal 100s of calls/texts a day from known burner apps) as well as physical damage to his car. The police did nothing at all, even with a step-by-step guide provided by said burner number apps for law enforcement (abuse@$burnerAppCompany.com). In the end we had to keep pressing the various app's support until they would blacklist my friends number completely from their app network. It was a huge PITA and made my friend's phone almost unusable (they would rotate numbers if he blocked them). Oh, and we knew exactly who was responsible, this wasn't even a "here is a lat/long" situation. The police are fucking worthless for things like this and from what I've heard from friends about their experience with stolen property they are useless on that front as well.
On the other end I have seen stories of cops showing up at someones house insisting they have someones macbook because find my said so when in reality it was the house next door.
I can understand why they would be hesitant when the find my data is not pin point accurate.
